Which integrated amp with Harbeths?

Looking to put together a very simple 2 channel system around Harbeth Super HL5s, Ayre CX-7e redbook player, and (rarely) play some vinyl. Asking for your reccomendations on an integrated amp that would match well with the Harbeths. I've auditioned the Krell 400xi, and will soon try the Plinius 9100/9200. Budget of $2,500.+/-, used on A'gon. Jazz, blues, folk, standards and especially female vocals are my main point of interest. Thanks in advance for your input.
